"They have left it only to-night," said Decius, clambering up the mound of earth and sniffing the air. "Had it been a day old, we should have smelt it long ago, though the wind blows from us."
Then, as they descended and traversed the silent lanes, a puzzled expression came to his face, and he halted from time to time.
Sergius eyed him inquiringly.
"Do you not smell fresh blood?" said the veteran, at last. "I remember when we marched with Lucius Aemilius, after the Gauls had beaten the praetor's army at Clusium. There were ten thousand men just slain, and the air was salt like the sea—by Jupiter! What is this?"
Resuming their advance, they had come upon a space of open ground near the centre of the camp, doubtless the spot reserved for a market; but what meat was it that cumbered the shambles, without buyer or seller? Piled in ghastly heaps, or covering the ground two and three deep, lay a fresh-reaped harvest of corpses, stripped, distorted, gleaming in the moonlight. Could it be that the camp had been taken? But these were no African dead, nor yet was this a Roman camp. There was a set deliberation, too, about the slaughter, that told no tale of battle.
Suddenly Decius cried out and, stooping down, raised the hands of one of the victims—hands upon which the shackles still hung.
"Slaves," murmured Sergius; "but why—"
"Say, rather, prisoners," said the centurion, grimly.
Sergius struck his thigh. It was all clear to him now.
"May the plague fall upon him! may he go to a thousand crosses! Do you not see? He is escaping. He has made for the passes and slain his prisoners, that they may not hamper his march. Who knows but that by now he is on the road to Rome? Gods! This was Hostilius' duty and mine, and we wasted our time and our men on a few score of miserable Numidians. Come, my Marcus, come: there are no such things as wounds or weariness or caution. We must reach the dictator at once, and may the gods grant that it be not too late!"
